MAURICE J.,WALSH, OF NEW YORK, N. Y., ASSIGNOR, BY MESNE ASSIGN- MENTS, TO MARY C. WALSH, OF SAME PLACE.

APPARATUS FOR SPECIFICATION forming part of Letters Patent No. 263,263, dated August 22, 1882.

Application filed May 19,1882. (No model.) f

To all whom it may concern Be it known that I, MAURICE J. WALSH, of, New York, in the county and State of New York, have invented a certain new and useful Improvement in Apparatus for Heating Gars,

of which the following is a specification.

Mypresentimprovementrelatesto apparatus for heating cars, which consists essentially of two pipes, arranged one within the other, passing through the cars to be heated, and flexible pipes extending between such pipes of different cars, all being adapted to convey a heating agenti'rom a locomotive or other source of supply through the train and back again.

I5 My improvementconsistsin the combination, with pipes, arranged one within another, for conveying a heating agent back and forth through a ear, of a cock communicating with the said pipes, and two separate flexible pipes,

zo arranged adjacent to each other, so as to be independently accessible, and communicating with said cock. The flexible pipes so arranged are more accessible than if arranged one within the other, and hence are in this respect more convenient. They are at the free ends provided with coupling-pieces, whereby they may be connected to similar sections belonging to another car.

In the accompanying drawings, Figure l is 3o a longitudinal section of two pipes extending,

onewithin the other, through a car, two flexible pipes, a cock, and coupling. Fig. 2 is a section of one of the coupling-pieces, taken in a plane at right angles to that in which it is shown in Fig. l; and Fig. 3 is a face view of the coupling-piece.

Similar letters of reference designate corresponding parts in all the ligures.

A designates a pipe, which may be made of 4o metal, whereby a heating agent is conveyed from a locomotive or other source of supply through a car.

B designates a pipe arranged within the former, and which may also be made of metal,

.t5 whereby the heating agent is conveyed back again. These pipes are screwed into the harrel or shell of a cock, C.

A B designate two flexible pipes, made ot' any suitable material, which are secured in 5o sockets a in the barrel or shell of the cock C by means of glands b c, or otherwise. These liexible pipes are to extend beyond the ear and to he connected by couplings D to similar Ilexible pipes belonging to an adjacent car. The object of these pipes is to afford a yielding connection between the pipes A B of the different cars, adapted to accommodate itself to the motion which cars invariably have relatively to each other. rIlhe flexible pipes are secured in sockets d, with which the coupling- 6o pieces are provided, by means of glands @for other devices. Both the flexible pipes are exposed, so as to be independently accessible. The plug ot' the cock G has a port, g, which, when the plug is properly turned, will establish communication between the pipe A and the tlexible pipe A and a port, 7l, which at the saine time will establish communication between the pipe B and the flexible pipe B. It also has a port, t', consisting of a mere cavity 7o or recess in its exterior, which, when the plug is turned so as to cut off communication between the pipes A A and B B', will establish communication between the pipes A B. Ihe use of this port is principally to return the healing agent from the end of the pipe A at the rear of a car to the corresponding end ot' the pipe B. -The coupling-pieces have each a rigid hook,j, adapted to engage with a pivoted hook, 7c, in the other, the pivoted hooks 8o being provided with handles whereby they may be conveniently manipulated. The flexible pipes are severally much more accessible than it' one were arranged within the other, and hence either may be easily and quickly repaired without disturbing the other.

What I claim as myinvention, and desire to secure by Letters Patent, is-

1. The combination, with pipes, arranged one within the other, for conveying a heating 9o agent back and forth through a car, of a cock and two separate flexible pipes, arranged so as to be independently accessible and extending beyond the car, substantially as specified.

2. The combination, with pipes, arranged one within the other, for conveying a heating agent back and forth through a car, of a cock and two separate flexible pipes, arranged so as to be independently accessible, extending beyond the car, and provided with coupling- 10a pieces, substantially as specified.
